This-invention relates in gen eral to bean .snippers and morein particularitoan im--V iroved mechanism jarticularh desi 'ned for" supporting the cutting-knife thereof. 1

.5; In my Patent No, 1,336,991,1ssued April 13,1920, 1' described a machine-forreceiving what are commonly; called string beans and automatically fsnipping the pends thereof.

Among the essential features of the machine p described tliereinwas an; improved type of ping ;.of f of the projecting ends of the beans'. The; knife? was mounted: in a slide 1 and i. a;

i ineans was,provide'd for reciprooating said described in my prior patent 'just referred 1 to actuate in a most desirable manner and.

these are preserved to the; present vtime. I have foundb-y repeated experiment and conv stant usesince thetime offiling application for my PIlODPELlIGIlt'tl'llt'bhe slldll'lg111G111? bets on whichlthefknifeis mounted can be improved, although in its ,.original' form it'- functions in a :satisfactorymanner, 1 I

vsuch gritty material may cause anabrasion of the metal surfaces andiwearrupon the sliding" members. A reciprocation ,o f, the knife inthe same 'horizontal' 'plane, however,

",isvery desirable'l One object of the 'presentginvention,therefore, is to provide a different andimproved' mechanism whereby taid knife may, be re+ ciprocated. in a horizontal plane; 5 Another object of the invention isthe provision of improved bean snipper embodying suchmechanism'l A further'object of the invention is the provision of an unique mechanical move ment which may be employed for obtaining a reciprocatory movementiofa member in a hOifizontalphn I g,

the r f general type as shownin my prior patent and is provided withia plurality of aper-. turesdesignated 15, through which the ends ofthebeans are adapted to project whereby i they will be snipped in a manner to be described. WVithin the cylinder 14 is a continuousbafileon the order-of an Archimedean scr'ew (not shown in detail) designed to feed the beans continuously through the cylinder.

Thelmot ve power for,"sa'idbean shipper is furnished to a pul1ey16 by: means ofa belt (not shown which leads to a suitable source'of power (not shown). The pulley' 16 is mounted on a shaft '17 journalledo in suitable bearings,- and supports aworm gear 18, which meshes with a ring gear 19, said i ring gear 19 beingsecured integrally to the cylinder-'14:. i 'A -spu-r gear 20," also Sec'uredto sald shaft 1-7 meshes with a-pinion. 21 secu ,Onfa

ner'inwhich I secure a continuous pressure:

of the knife e 6 in the direction of the cylinder. Referring particularly to Figurie 4,

itrwill be seen that a rod 570 isrotatably seis cured in the casting 41, and has secured thereto a dog 51 (Figure 3) which engages H a portion of oi t'hv. The rod spring52, which coil spring 52 is secured to a portion of the casting 41 The coil spring 52 is constantly under tension so that it thefkn'ife support member 43 has" secured 'thereto a coil tends at alltimes to twist the rodr50 toward the cylinder, This results in a gradual presi p sure on theopiyot member 43U0rfttbywthe dogs 51. In this manner the knifeis always 7 thereto.

"The, construction of the' kn'ife members; is" such" that when the "knife is forced away from the cylindervthesupport members are freed" from engagement with the dogs 51, andhence also from all'lnfluence by the springs 52; T1ieknifewi1l were; 7
